2011-02-17USB: isp1760: Implement solution for erratum 2Sebastian Andrzej Siewior
The document says: |2.1 Problem description | When at least two USB devices are simultaneously running, it is observed that | sometimes the INT corresponding to one of the USB devices stops occurring. This may | be observed sometimes with USB-to-serial or USB-to-network devices. | The problem is not noticed when only USB mass storage devices are running. |2.2 Implication | This issue is because of the clearing of the respective Done Map bit on reading the ATL | PTD Done Map register when an INT is generated by another PTD completion, but is not | found set on that read access. In this situation, the respective Done Map bit will remain | reset and no further INT will be asserted so the data transfer corresponding to that USB | device will stop. |2.3 Workaround | An SOF INT can be used instead of an ATL INT with polling on Done bits. A time-out can | be implemented and if a certain Done bit is never set, verification of the PTD completion | can be done by reading PTD contents (valid bit). | This is a proven workaround implemented in software. Russell King run into this with an USB-to-serial converter. This patch implements his suggestion to enable the high frequent SOF interrupt only at the time we have ATL packages queued. It goes even one step further and enables the SOF interrupt only if we have more than one ATL packet queued at the same time.

2011-02-17USB: s3c2410_udc: Add handling for S3C244X dual-packet modeFabian Godehardt
This is a patch that seems to make the USB hangs on the S3C244X go away. At least a good amount of ping torture didn't make them come back so far. The issue is that, if there are several back-to-back packets, sometimes no interrupt is generated for one of them. This seems to be caused by the mysterious dual packet mode, which the USB hardware enters automatically if the endpoint size is half that of the FIFO. (On the 244X, this is the normal situation for bulk data endpoints.) There is also a timing factor in this. It seems that what happens is that the USB hardware automatically sends an acknowledgement if there is only one packet in the FIFO (the FIFO has space for two). If another packet arrives before the host has retrieved and acknowledged the previous one, no interrupt is generated for that second one. However, there may be an indication. There is one undocumented bit (none of the 244x manuals document it), OUT_CRS1_REG[1], that seems to be set suspiciously often when this condition occurs. There is also CLR_DATA_TOGGLE, OUT_CRS1_REG[7], which may have a function related to this. (The Samsung manual is rather terse on that, as usual.) This needs to be examined further. For now, the patch seems to do the trick. Signed-off-by: Vasily Khoruzhick <anarsoul@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

Add an m68k/coldfire optimized memmove() function for the m68knommu arch. This is the same function as used by m68k. Simple speed tests show this is faster once buffers are larger than 4 bytes, and significantly faster on much larger buffers (4 times faster above about 100 bytes). This also goes part of the way to fixing a regression caused by commit ea61bc461d09e8d331a307916530aaae808c72a2 ("m68k/m68knommu: merge MMU and non-MMU string.h"), which breaks non-coldfire non-mmu builds (which is the 68x328 and 68360 families).

2011-02-15pci: use security_capable() when checking capablities during config space readChris Wright
This reintroduces commit 47970b1b which was subsequently reverted as f00eaeea. The original change was broken and caused X startup failures and generally made privileged processes incapable of reading device dependent config space. The normal capable() interface returns true on success, but the LSM interface returns 0 on success. This thinko is now fixed in this patch, and has been confirmed to work properly. So, once again...Eric Paris noted that commit de139a3 ("pci: check caps from sysfs file open to read device dependent config space") caused the capability check to bypass security modules and potentially auditing. Rectify this by calling security_capable() when checking the open file's capabilities for config space reads.
